What Causes Red Blotches On Either Side Of Torso And Hips?

I have multiple red blotches on both sides of my torso towards my hips. They don't itch and if I couldn't see them I wouldn't know they exist. I'm a wrestler and am wondering if this could be a bacterial or fungal disease from the mat? I've started to put Lotrimin on the blotches before I go to bed but it doesn't seem to be helping. Suggestions?
